Erlig Khan

In the Asia section of the Musical Instrument Museum, people gasp as they approach the exhibit from Mongolia.

Looming high into the air stands Erlig Khan, dressed for the traditional Buddhist Tsam Masked Dance.
*Tsam means a dance of the Buddah.

The Lord of The Underworld, Erlig Khan appears at the end of the performance to banish evil.

Good thing he comes at the end because I think this guy would clear a room pretty fast.
