It appears that Luna is noticing exactly what he was afraid of - that the chair is changing Onyx, and not for the better. After the successful revolution led by the Disturbers, the Upperworld now lies under the dominion of Onyx.

Unfortunately, the current that provides the life energy for the orbs now runs through him, rendering him physically unable to leave the throne or touch anyone without immediately vaporizing them. Onyx and Luna are now the only half-humanoids in the Upperworld emotionally tied together, for better or worse - and they both suffer greatly from being kept apart. To ameliorate the situation at hand, Griffin and Evander suggest a potential solution - and the answer just might lie in Onyx’s past.

After constructing a time machine, Griffin journeys back to Earth year 1790, when Onyx’s mother lived in Puritan America and conceived him. By watching her closely, there is a small chance that he might be able to pinpoint the exact moment when her choices deviated from the master plan - and those coordinates just might have the power to set Onyx free.

Will Onyx be able to tolerate being imprisoned long enough for Griffin to save him? Or will he degenerate long before they can manage to set him free, leaving them no choice but to pull the kill switch on the Upperworld once and for all? Don’t miss the epic conclusion to The Upperworld Series!
