Does becoming a shard holder (? my lingo is fuzzy it’s been too long) count as “dead”? E.g. Harmony after mistborn trilogy 1

@Ziddletwix nope, shards' vessels still count as alive since they can be "killed".

From the Coppermind:

While unable to die from disease or old age, Vessels can be killed in specific circumstances. Such as when killed or Splintered by another Vessel, or when struck by Nightblood. They can also be killed if they break an oath, which leaves holes in them that can be exploited to kill them.
