I loved the Prydain books when I was a kid. Couldn't decide whether Taran or Eilonwy was my favorite character.

I did find an old interview with Kari Matchett (Siobhan Beckett) where she said they offered her a permanent place in the cast as a full-time character in the second season, but then she didn't appear in several episodes, so she took a job in another series that was full-time...and there went whatever story arc they were building with Liam and his parents.
