RET-CON: What really happened when The Stag Lord met his end?

After Uldons heroic leap from the second story balcony of the Forts tower, both he and the Stag Lord came crashing through the first story roof and onto the ground. Uldons battle reflexes allowed his mind to recover quickly, but his body was beaten and torn from the battle, he could only watch as the Stag Lord leveled a deadly arrow at his eye at point blank range... Uldon would finally meet his ancestors...
At the last moment the Stag Lords neck errupts in a spray of blood! The mans hands weaken and he drops his bow, one hand slowly lifting to pull a single paper playing card from the gushing wound...
He stares at the card in disbelief, then slowly tracks his gaze upward through the hole above him.
There, on the upper landing Uldon had flung himself from, bathed in bright sunlight from the noon day sun stood the groups new comer! A man known only as doc, in his hand rested a deck of simple playing cards...
Runes flash suddenly to life all over the Stag Lords body, burning a brilliant first blue! The Stag Lord convulses in pain as the runes seem to rip themselves from his body and flow upward into the helm that granted him his name. In another blinding flash the blue fire shoots upwards and wraps itself around Doc! Rather than burn the man though the runes seem to gently caress him as they settle down onto his body in an intricate pattern, and suddenly wink out of existence...
It is thusly that yet another Mythic hero has been born... claiming the Stag Lords Mythic Power as his own!
