There is no sun for Helkaraxe and the planet and moons are visible only as black silhouettes against the dusting of stars, like the illo below. After being warned that gazing into the dark has bad effect - leading in some cases to catatonia, four PCs tried it, and two got caught.
The balance was spent trying to get then to WANT to come out of it! They were shot full of adrenaline and packed in ice, coddled and strapped down. Some really terrific roleplaying from my Sunday gang! Thank you all guys!
