Astram was a druid who lived near the end of the God Wars. Astram is only mentioned in the FunOrb strategy game, Armies of Gielinor.
In Armies of Gielinor, Astram is quoted in starting screen of the level "Pack Mentality" during the Guthix Awakens campaign. They noted that dire wolves brought to White Wolf Mountain by Seren's followers could lead to a disastrous ecological imbalance, as the mountain wasn't the dire wolves' natural habitat, and advised others to deal with the dire wolves in order to avert the possibility of an ecological imbalance. Given that Astram lived during the Third Age, Astram is presumably deceased.
The Astram Farm on the road between Taverley and Burthorpe is named after them.
