basic terrain of the planet:

.landscape

   .dark

   .rocky and steep hills

   .lava ponds

   .gravestones spawn around the terrain/area

   .trees without leaves so the planet has a sense of no life

.what should spawn

   .weeping angels, they move when you aren't looking at them and when they are close enough they do an insane amount of damage (melee)

   .wooden cyber men, these shoot fire and instead of saying delete they say incinerate

   .the rusty old stone Daleks and the original Daleks, they have deep metallic sounds and shoot normal blast

   .the silence, are very quick and fire lightning down from the sky

   .whispermen, do what ever damage they did in the show

key locations:

   .the town of Christmas:

   .it is not rocky here

   .not as dark

   .snow is here

   .only place on trenzalore where the weather changes (snowing)

day light cycle:

   .always dark

   .every 7 minutes or so it is day but only last 30 seconds or so

There should be 2 Trenzalore Time zones the 1 after The doctors Regeneration and where the the doctor has died like the city Christmas and then Trenzalore
