Pike's freaking Deep Gnome? I had her pegged as a Forest or Rock Gnome.
Yup, when they originally did intro videos for their livestrwam, the Tricklefoots were called out as Deep Gnomes (and she does know Undercommon), but oer the fan Wiki it does seem somewhat unclear:
The Trickfoot gnomish lineage
During
Campaign One it was mentioned that Pike's ancestors were deep gnomes,
[7][8] and this is reflected in certain family traits, like the knowledge of
Undercommon that has been passed down the generations to reach Pike's.
[9] However, members of this family do not have the usual appearance associated with nether gnomes, displaying more human-like skin tones than the more common grayish; and without abilities of this subrace, such as a superior darkvision.
[10] At times Pike has been referred to as a
rock gnome,
[11] while at others the Trickfoots are referred to as a clan of
forest gnomes,
[12] although the
Champion of Sarenrae hasn't manifested specific abilities of either of those subraces either.
The simplest explanation is that, as Pike explains in her story, her ancestors were deep gnomes who settled on the surface, and over the generations, marriages with forest and rock gnomes diluted the most characteristic features of the
Underdark subrace. The fact that they are considered a clan and that Pike has several relatives also implies that the Trickfoots are generally considered forest gnomes (in part because of their ancestral home near the
Bramblewood Forest)
[13] and that only specific branches of the family trace their origins to the blood of the nether gnomes.
