The Death Wyvern is the first boss encountered in Hexen, which guards the exit to the Hypostyle. Killing the Death Wyvern is the key to unlocking the bars in front of the exit, and hence completing the Shadow Wood hub. The Death Wyvern is a returning (non-boss) enemy in Hexen: Deathkings of the Dark Citadel, where four of them are patrolling the outdoor areas of a single level.
