Yrn-fae
Yrn-fae, the Lighting Bolt from a Summer Sky, was a Saim-Hann Swooping Hawk Exarch who was part of Chieftain Fell Winter's forces[1b] that invaded the Imperium world Dellerax. The Eldar later clashed with Cadian Imperial Guard Regiments, led by Commander Pask, when they came to the world's aid[1a] and Yrn-fae was killed by the Guard in The Battle of Phantomfall.[1b]
