Ages of Doubt

The Ages of Doubt are eras in Covenant history following the Age of Conversion, where the effects of the previous eras are dealt with.

The last Age of Doubt, the 29th, ended in 2525, just months before the discovery of Humanity. This also marked the beginning of the 9th Age of Reclamation.

The Ages of Doubt are represented by the opal stone.
