The Silaes Tairn are the foremost outside experts on Xen’drik’s ruins. Sensationalized reports from Stormreach have painted them as brutal warriors who seek to literally repeat the actions of their ancestors. In truth, the Silaes Tairn do not come to Xen’drik to defeat the descendants of the ancient giants and drow – they seek to dismantle the creations of the ancient giants.
Many of the Silaes Tairn are not martial exemplars but artificers and trap experts; their role is to disarm traps, deconstruct weapons, and generally clean up the dangerous remnants of the Age of Giants. This naturally puts them into conflict with explorers from Khorvaire, who seek to exploit these left-behind treasures.
Many Silaes Tairn clans have established friendly relations with indigenous drow, even to the point of exchanging members – some Silaes Tairn choose to stay and live their lives in Xen’drik, while some drow have gained patron spirits and joined the Tairndal.
