Birthsigns are powerful blessings granted by the Constellations that spread across the skies of Tamriel. Each constellation falls under the protection of one of the Guardians: The Mage, The Thief, and The Warrior. Once you select a Birthsign, your character is locked to the Birthsigns that fall under the protection of that Constellation's Guardian.
Birthsigns are selected when you create a character and can be exchanged for another Birthsign with the same Guardian by activating Standing Stones.
The Mage birthsign and its three charges. Once you select one of these Birthsigns, you may not select any birthsign of the other two Guardians or The Serpent.
