The cover to GURPS Ultra-Tech for 4th Edition.

TL12 (The Age of Miracles) is the upper limit of the GURPS TL system because even understanding a TL 4 levels above your own (TL8 for us when GURPS originally came out making TL11 (The Age of Exotic Matter) the absolute limit) is impossible.

There can be TLs higher then this but they are totally incomprehensible. Pure superscience devices are listed on TL^ (Superscience Tech)
