The mountain where the blackbloom grows

The mountain on top of which the blackbloom grows has yet to be named. (Blackbloom Ridge has been suggested at the entry about the Wandering Bayou .)

When Lord Death was killed by his daughter Jealousy, his blood rained down into a pond at the top of a mountain, where the blackblooms now grow.
