Absorb is a damage prevention keyword ability, written as Absorb N, where N is any natural number. It prevents N damage from each single source that deals damage to the creature. Absorb was introduced in Future Sight. By its nature as a damage prevention ability, this is a white ability. It has only been printed on one card so far, the timeshifted Lymph Sliver.
