After a long silence, Gregori makes contact with Diego. Río enlists the help of Misnyl to get her and Diego into the palace. Tosh and Athena come to an understanding with Finellen. Dona is nearly past hope but there might be a way for Diego to save her, although the end result wouldn't be ideal.

Ríona and Diego make their way down the mine with Dianne. Tosh "saves Athena's ass". Dianne gives more information about what happened the last time Ardere allowed outsiders in. Diego and Río fervidly disagree about the role Dianne should play moving forward. The D'artagnans are finally reunited, but the tunnels aren't vacant.

Athena connects with ancient history. Tosh makes a discovery. Ríona reaches out to no avail. Diego and Río make plans to help their missing friends, but not without assistance and insight from Dona first.
