Shield of Dalera

The Shield of Dalera were small Ancient devices that were created by the Lantean known as Dalera. They were similar in appearance to Ancient personal shields but their purpose was very different. The Shields of Dalera actually generated electromagnetic fields that could shut down advanced pieces of technology; whether its Wraith, Ancient or Human. They were part of a elaborate defense system created by Dalera in order to protect the Dalerans.

The Shield of Dalera could only be activated by someone with the Ancient gene. When detecting a piece of technology, the Shields would glow which would signify both their use and the possibility of enemies approaching.
