Mara Sov — Riven's Wishes IV

"Your next challenge awaits you in the Blind Well.

"The power of the Well is never to be taken lightly. As vital as it proved during our efforts to secure Riven's last clutch, it is just as capable of opening gateways to planes not even your Ghost could withstand.

"That is, if its use were not constrained by the mechanism that houses it. It's been calibrated for Guardians, after all. The risk is minimal."

There is a glint in Mara's eyes that suggests she may be teasing you. "Fight well."
