  We present the distance-calibrated spectral energy distribution (SED) of
TRAPPIST-1 using a new medium resolution (R~6000) near-infrared FIRE spectrum
and its Gaia parallax. We report an updated bolometric luminosity (Lbol) of
-3.216+/-0.016, along with semi-empirical fundamental parameters: effective
temperature Teff=2628+/-42 K, mass=90+/-8 MJup, radius=1.16+/-0.03 RJup, and
logg=5.21+/-0.06 dex. It's kinematics point toward an older age while spectral
indices indicate youth therefore, we compare the overall SED and near-infrared
bands of TRAPPIST-1 to field-age, low-gravity, and low-metallicity dwarfs of
similar Teff and Lbol. We find field dwarfs of similar Teff and Lbol best fit
the overall and band-by-band features of TRAPPIST-1. Additionally, we present
new Allers & Liu 2013 spectral indices for the SpeX SXD and FIRE spectra of
TRAPPIST-1, both classifying it as intermediate gravity. Examining Teff, Lbol,
and absolute JHKW1W2 magnitudes versus optical spectral type places TRAPPIST-1
in an ambiguous location containing both field- and intermediate-gravity
sources. Kinematics place TRAPPIST-1 within a subpopulation of
intermediate-gravity sources lacking bonafide membership in a moving group with
higher tangential and UVW velocities. We conclude that TRAPPIST-1 is a
field-age source with subtle spectral features reminiscent of a low surface
gravity object. To resolve the cause of TRAPPIST-1's intermediate gravity
indicators we speculate two avenues which might be correlated to inflate the
radius: (1) magnetic activity or (2) tidal interactions from planets. We find
the M8 dwarf LHS 132 is an excellent match to TRAPPIST-1's spectral
peculiarities along with the M9 beta dwarf 2MASS J10220489+0200477, the L1 beta
2MASS J10224821+5825453, and the L0 beta 2MASS J23224684-3133231 which have
distinct kinematics making all three intriguing targets for future exoplanet
studies.
