Exactly! When Ishy was around, there was a weaker version of a fade with special abilities!
Only after Ishy died, there is a stronger version Fade around.
In and by itself, that could be coincidence. But given the rest of the clues and hints, I seriously doubt that's the case.

What should also make you wonder, is the following;
Why was Ishamael the only Chosen to even know about the existence of SHv0.5? Why was SHvo.5 kept secret by Shai'tan except to Ishamael. Because Ishamael was -literally- part of that deal.

Let's take a closer look about the one 'project' in the early books where we know for 100% sure that Ishamael & "SHv0.5"
cooperated: Bors (Carridin).

- First, Carridin recieves orders from Ba'alzamon in the prologue of TGH. Two funny details about that prologue: (1) Ba'alzamon is a burned man (wounded) hovering above a fade! Talk about a hint!.
(2) Carridin thinks to himself at one time "how his mind could understand to Myrddraal cowering in the figures shadow "without splitting". That's just brilliant RJ humor for you.
back on track though; Carridin get's his orders from Ishamael. Right? Right!

Day 340 / Saban-11; (0 days)
- Then, in the prologue of TDR Carridin is visited by SHv0.5.
SHv0.5 knows the orders of Carridin given by Ishamael. (finding and killing Rand & work to be done on Almoth Plain were orders from Ishamael, refered to by SHv0.5). At the very least, this proves that Ishamael & SHv0.5 work together very closely.
Right? Right!
- Carridin is ordered by a SHv0.5 to kill Rand within a month.

Day 368 / Aine-11; (+28 days, 1 month after promise)
- Jaichim Carridin's sister, Dealda, is carried off from her bridal feast by a Myrddraal.

Day 396 / Adar-11; (+56 days, 2 months after promise)
- Jaichim Carridin's cousin is found skinned alive in his bedchamber.

Day 422 / Saven-9; (+82 days, almost 3 months after promise)
- Ishamael dies.

Day 452 / Amadaine-11; (+112 days, exactly 4 months after promise)
- Carridin thinks about two family members that died two and three months ago. No other family member has died yet for ‘2 whole months’. He should have heard of a third family death by now, because it should have happened 28 days earlier and there is still plenty of family left;
- Later that same day, he frantically tells Liandrin he still has ‘cousins, nephews, nieces and another sister’, so that’s at least 7 more months he can survive on ‘borrowed time’.

It’s very odd that around the same time that Ishamael was killed, the killing of Carridins family members stops! If SHv0.5 was a completely separate being, why didn’t the killing of Carridins family continue?
SHv0.5 made that promise to Carridin.
SHv0.5 made sure the first two family members were killed exactly as promised!

Day 652 / Taisham-14; (+312 days, little over 11 months after promise)
- Sammael tells Carridin his last family member (Vanora) died ‘recently’. Sammael says that someone is making sure at least some of Ishamaels commands are still carries out.
According to the Myrddraals promise, it should have happened 4 days earlier; exactly at the 11 month mark. We can conclude Carridin had a total of 10 family members that ‘shared his blood’.

- Apart from that weird hiatus in the murders of Carridins family around the time of Ishamaels dying, the murdering has taken place so that Vanora that died ‘recently’ was the last one to go.

Day 687 / Jumara-21; (+347 days, 12 months and one week have passed)
- Jaichim Carridin his time & family has ran out and he is killed as ordered by Moridin.

Let's add things up:
So first Ba’alzamon (a horribly burned man hovering above a Myrddraal) gives Carridin orders. SHv0.5 comes to threathen Carridin, fully aware of Ba’alzamons orders and SHv0.5 makes a promise to kill one of his blood-kin for every month that Rand lives. The promise is kept up until Ishamael dies and at the same time the killing stops for at least one month, perhaps two. Per Sammaels words halfway ACoS, we know that someone had been making sure that at least some of Ishamaels orders have been carries out up until then. (Sammael is referring to the killing of Carridins relatives, so Ishamael must have been fully aware of what SHv0.5 promised Carridin) Finally, it is Moridin that keeps SHv0.5 its promise and orders Carridins death.
Also take into consideration that none of the Chosen knew of SHv0.5’s existence, prior to LOC, whereas Ishamael has always known about it’s existence. Of course Ishamael did know; him and SHv0.5 were always linked, part of one and the same being.
Shai’tan deliberately kept it from all the other Chosen, because if that’s what it takes to become Nae’Blis, noone would want to be half a step below the Dark One.

Concluding, I think RJ's remark that the fade in the prologue of TDR visiting Carridin strengthens my case that Ishamael has always been linked to a fade somehow.


Erm. What's your point? How does this disprove a Slayer-like connection to Moridin? That we know Shaidar Haran is a special Myrddraal that can channel is a point in my favor I think;
To be able to channel you need a "living mind". Where do you think Shaidar Haran gets his living mind from? (TEotW, Chapter 18 - The Caemlyn Road)
How about from what's left of Ishamael mind..?

Like I said in my previous post; think Slayer.

Slayer is one being, yet it shares two seperate minds (Isam & Luc) that can think of eachother as being seperate indivuduals with their own feelings/ emotion/ likes & dislikes. Isam isn't Luc. Luc isn't Isam. Yet both are fused together in Slayer. one of the two thinks at any given time, yet they share eachothers memories.

I see the same happening in the Nae'Blis.
Just like Slayer (Isam & Luc fused together) is 24/7, so is the Nae'Blis (Moridin & Shaidar Haran fused together) 24/7.
In that quote you refer to by RJ, RJ specifically refers to a question about Shaidar Haran as "this creature".
Why didn't het just call it "this Myrddraal"...?
