Ostav
The Margin-Keeper
ShadowHarmonist★★★★I will keep the names they scrape away.

Profile
A copyist of the archives of Anemhal, where names are erased from the records on Ilvesk's orders. Ostav copies them first, in the margins, in a private code. At seventeen, as an apprentice, he watched the girl at the next desk run, and has never forgiven himself for not running with her.
In their words
- Forgive me. I remember things. It is a terrible habit.
- Age
- 34
- From
- Anemhal, Dravna
- Anchor
- Ildavna
- Weapon
- A heavy ledger bound in iron, and a bone stylus

Ethereal Path
170 of its 255 stars can be lit: two shared zones, then one specialization to choose.
From Oath Tier V, once 60% of Mastery is lit, choose one specialization. The other one stays visible but closed. Switching costs 20,000 Lume and gives back the points spent.
