 There are those who play with time travel in the annals of  the epoch of the Human Space Empire & though they know a bit about the angles of time with the invention of the Three Light Drive.  These things dwell along the edges of the the angles of time. They feed off & lust after the essence of one's soul & those who emotions echo through time. 
They in turn feed the Hounds_of_Tindalos but those are far worse then these creatures. For these feed on the seconds, minutes, & hours  of a person's soul bit by bit & drop by drop as time drips away into eternity.  They will appear from any colored surface around a person but can't pass through the color black for it reminds them of the great betrayal.  
 The future & the past are nothing to them as the plunge from world to world following in the wake of  the Outer Gods & the Great Old Ones. 
  A person may catch a blue flicker in a mirror followed by the opening of their mouths & sting of their barbed tongue  as it lashes into the back of one. 

Some super science powers will keep the 12 foot long monsters at bay but they will know the next moment to strike & travel there. Once hit a person must save versus poison or roll 1d20 every 6 rounds to see how many years from your life you lose as the worm devours them. The chrono poison coursing through one calls to the lean & hungry hounds. They will sense it as a dinner bell in the dark of space & come nosing through time that is unless the worms get you first. The poison can be tracked through time & space itself & only a barrier of aluminum will stop the signal. A fine powder of the substance will stop it for a time but then another saving throw must be rolled. A vicious cycle indeed. 
 There are reports of some scientists who can cure this poison but the cost is very high indeed.  A specially tuned z ray rifle may slow these creatures down or destroy them but the modifications are known to very few fanatics & madmen on Terra Entra III. The world slowly out of sink with the rest of the universe.
