Thaszerain
From SDSDWiki
Thaszerain was a white dragon who participated in the breaking of the Siege of Swansing Keep in 243. He allied with the Free Company of the Wolf, although the terms of that agreement are unclear, as white dragons are typically evil. He carried the members of that party into battle, but other information about his participation is lost.
Appearance
As a white dragon, Thaszerain would have had icy white scales and access to a freezing breath. His age is unknown, so his size and flight abilities are unclear.
