[hider=Dragon, Underwyrms]

[h3]Dragon, Underwyrms[/h3]
[b]Racial bonus:[/b] +30 in Aerobatics, Acrobatics, or Stealth
Special abilities: echolocation, geomagnetic sensitivity, flight. Cannot manipulate humanoid weapons or tools.

[b]Echolocation:[/b] Underwyrms are entirely blind and navigate primarily by echolocation. They have excellent hearing, of course, but this renders them sensitive to loud or confusing noises.

[b]Geomagnetic Sensitivity:[/b] Much like rats and sharks, Underwyrms can sense their orientation with regards to the earth's magnetic field. This helps them to always maintain a sense of direction, regardless of where they are. However, strong magnetic fields may cause severe disorientation, nausea, or loss of balance.

Gender | Min height | Max height | Min weight
Male | 5'6" | 6'5” | 1200 lb
Female | 6' | 8' | 1600 lb

Underwyrms are the descendants of a dragon native to the Feywild, whose ancestors were summoned to this world by wizards and had eventually fallen to subjugation by the Drow. They have proven to be astonishingly adaptable over the centuries, and the Drow have bred them to thrive in the vast caverns and subterranean tunnels which they inhabit. Their eyes are vestigial, their wings narrow and fleet - adapted for agile flight in small, swift bursts, with hooks at the joints that help these creatures climb.

Though intelligent and capable of speech, Underwyrms have never developed an independent society: they are loosely matriarchal, much like the Drow who shaped them, but there is no tendency to form stable flocks. Rather, these creatures move between social groups with little sense of attachment, and status is determined largely by personal charisma and dominance.

Traditionally rejecting the worship of Lolth in favor of reverence toward an entity of which they speak only as "the dark", these dragons have largely preferred to accompany those Drow who have migrated away from those lands devoted to the spider god. They are few in number and largely nocturnal, when seen above-ground, and often tend to be xenophobic. They tend naturally to be friendly toward the Drow, but every living specimen would feel an inexplicable fascination toward those races native to the Feywild - a magnetism that has continued since the death of magic.[/hider]
