The Lost Crystal of Power is an ancient source of immense energy coveted by Lyric the Last Ancient. His first attempt to stop it was foiled by his fellow Ancients, who shattered the crystal and used its power to trap Lyric. Fearing his eventual escape, the Ancients then hid the fragments of the crystal throughout the Sonic Boom Zone. Thousands of years later Lyric would resume his search, and his quest would lead to encounters with Shadow the Hedgehog and Amy Rose. (SB: SCDC)
