The NPC post will go up morning of the 15th and the poll will close midnight on the 16th so there's some time for discussion, yes!

Zero is the volunteer that was chosen to ask Yggdrasil how to get Tyr's soul back during last month's plot event. She didn't actually get his soul, just the information on how to do so. The Travellers will know about him from this post awhile back, but other than that, there are no written records of him anywhere. Honir will be around in the new NPC post to keep spreading the word of Tyr too!
