Ydahri are newt-like inhabitants of Ydahr and distant cousins of the G'ahnli. Notable characteristics include feet like those of the gecko that adhere strongly when planted at the proper angle, enabling the Ydahri to climb vertically up walls (though not across horizontal ceilings). Because the borders of Ydahr's solar system have been closed to entry since late 2003, Ydahri who leave may not return; however, many young Ydahri have continued to leave.
