Christopher said "there have been at least a couple of OblivAeon shards written about in other Sentinel Comics character backstories". I agree the Scholar's stone may be one of them, it does not mean :
I've been wondering about Bugbear and his Bloodstone. I always assumed that was an oblivion shard.
The Bloodstone was made directly from Bugbear's life force and ancient magics.
I've often wondered what the pink crystal GloomWeaver holds is, but I doubt it is an OblivAeon shard. I don't know why, but the feel of it doesn't match the rest for some reason. I think it is a respresentation of Earth or the dreams of people or something. His connection to the realm he feeds on.
he said there was "at least 2". Just so we get the quote right here.
I guess the transcript I copied the quote from was wrong, then.
EDIT
Let's be precise.
Source : Matchstickman' transcript.
theshypinkiepie: @Gtgchristopher so would it be too much to ask how FT. Adamant got a hold of OblivAeon shards before his appearance at Ft. Adamant? (if I got the sequence of events right)
GTGChristopher: @Theshypinkiepie They must have found them somewhere. In fact, there have been at least a couple of OblivAeon shards written about in other Sentinel Comics character backstories, as well!
The " at least two" you are referring comes from :
DWSetback: Before the Void Guard reveal, how many Oblivion shards have we seen or heard about in the game?
GTGChristopher: @Dwsetback At least two
