A new couple of artifacts:
The Wing and the Key
These object are said to come from another dimension and to be nothing more than fragment of colour lost in the flux of time.
The Wing is a cape weaved with an iridiscent cloth that changes colour depending on the light, the Key is a diminutive trinket, suitable for a necklace or a bracelet, but so intricately decorated ones cannot hope to really understand its design.
The artifacts work in tandem: the bearer of the Wing is able to always know the location of the bearer of the Key, and to teleport in their location with a mere thought.
The bearer of the Key is able to know every thought of the bearer of the Wing and automatically succeds with a 10+ in every roll made to Aid them.
