Achernar...aka Alpha Eridani. That was where Redjac had one of its sprees, right? On the second planet in that system? Heliopolis City?
Different Achernar. That one was/is in Federation space. There's another Achernar in Romulan space, seen in Star Charts
(which is where I got it to use in Articles
as the seat of the Romulan State).
Err, huh? The Achernar in the Romulan map in Star Charts is
Alpha Eridani, the real Achernar, and "Wolf in the Fold" did mention that Heliopolis City was on Alpha Eridani II (the name Achernar wasn't used in the episode).
