Denkir system

Denkir is a star system that is in or near Federation space, somewhere in the galaxy's Alpha or Beta Quadrants.

History and specifics
On star charts, this system could be seen to be in the vicinity of McKnight's Planet, Alpha Shiro, Foster-D'Angelo and Eminiar

In the 2360s decade, this location was noted on a star chart showing deployment of Federation and Cardassian Union ships displayed in Captain Benjamin Maxwell's ready room aboard the starship USS Phoenix (NCC-65420). 

Alternate realities
On a 24th century viewscreen display of a tactical situation monitor in an alternate timeline where the Klingon Empire was at war with the United Federation of Planets in the year 2366, Denkir was listed on a star chart showing Klingon allied forces in relation to Federation positions. 

Background
The Denkir system was only listed on the "Yesterday's Enterprise" alternate timeline tactical situation monitor showing progress of the Klingon war with the Federation, and a later re-use of this chart in "The Wounded".
