A dozen years ago, two Ascalon explorers, Marshall Whitman and Tasca, planted a flag in the ground and declared this thin patch of the ground to be their base camp. Those days of peaceful exploration are now gone, replaced by ballistae, Deldrimor soldiers, and Dolyaks perched on the precipice of Grenth's Footprint.
Apart from the regular Tyrian musical score, this outpost is one of two in Tyria - the other being The Granite Citadel - that includes an additional musical composition, consisting mainly of flute and violin. That composition is called "Over the Shiverpeaks" in the Guild Wars Official Soundtrack.
Bug! There is part of the outpost near the portal where the music stops abruptly.
