Ishar as a dawnshard

[Infinity Sliver]

I was just wondering if Ishar could be a dawnshard. Part of their definition is "known to bind any creature voidish or mortal" and Ishar basically created the Oathpact(if i remember correctly),had powers before been a herald unlike the other heralds,and basically forced the knights radiant to follow the  Immortal Words ( if i remember correctly). Also,his powerset seems tied more to connection than anything and,I dunno,he seems like a very likely candidate to be a dawnshard.

He was also know as Binder of Gods.

i was thinking maybe he was a Dawnshard on Ashyn and was one of the one who burnt it.
