3. The presence of Dragon items on Freneskae indicates that, at one time or another, the Dragonkin spent some time on the plane, and one of them could have easily been killed during their time there. That being said, given the lack of any mention of their presence in either Zaros, Seren, or the Mahjarrat's memories, the Kin would have needed to have left Freneskae prior to their creation. This would have placed their time on Freneskae as being long before Guthix, the very first known false user/stone toucher, reached Gielinor. This makes it somewhat unlikely that the rage their curse causes would have been triggered yet, and the immortality they get from their curse makes it unlikely that anything else would have killed them at the time (unless, Mah finally waking up, emerging, and killing some of them is what prompted the kin to leave the plane).
