Deadeye

A deadeye is what a dead spren Shardblade is known as when in Shadesmar. In the Physical Realm, one is simply a Blade.
According to Brandon, readers can assume that there are more deadeyes wandering Shadesmar whose Shardblades have been lost, than there are ones that for whom their Shardblades have been kept.YouTube Spoiler Stream 4, 6/16/22
==Characteristics==
Dead Blades require ten heartbeats to appear.
They don't glow as living Blades do.
They each can't change their shapes.
They each need a gemstone within them so that they might be bonded.
When a dead Blade is dismissed, a deadeye spren stays in Shadesmar, rather than appearing in the Physical Realm like a living Blade's spren does.

==Notes==
While in conversation with Timbre, Venli learned that Timbre's grandfather (i.e., Ico's father?) was a spren killed by the Recreance.
Brandon has said that something weird is happening to make deadeyes. That they didn't exist before the Recreance. Further, that there should be a relationship there that reminds readers of something else they've seen in the cosmere.YouTube Spoiler Stream 1, 12/17/20
==Theory==
Readers have received multiple Words of Brandon indicating that deadeye spren are something new, and that old Radiants didn't ever have deadeyes. That he said the relationship should remind readers of something they've seen in the cosmere, what about the shadows from Threnody?
There are a few similarities. Mainly, a Shattered Shard (Ambition for Threnody, Honor for Roshar). Perhaps each their mannerisms are tied to the Shard that was there (i.e., the shadows from Ambition lash out and fight, whereas the deadeyes from Honor seek to uphold their duty as Shardblades).
