Old Mage's Treasure Tales

I tell tales old, I tell tales of new,
tales of adventure, my tales are true.
Some tales are joyful, some tales are bleak,
take heed of my tales, clues come from my beak.

Somewhere out there, in a comic of mine,
a tale hides a secret, clue by clue by line.
If you've read one through, and gathered them all,
pick your tale below, and answer my call.
