Here are the old, OLD raid sets from Helegrod, the original and only 24-man raid in LotRO. Although the raid is, in its current form, horrendously outdated, it's still run by many people for deeds and, occasionally, even fun. In the next update the huge instance will be split into separate wings, it can be scaled up to lv65 and there will be new challenges (hardmodes) in each boss encounter. We'll have to wait and see what they'll do with the current armour rewards.
Anyway, here are the Helegrod light armours. Note that these are all from the era of Silly Hat Designs. I have a feeling the artist team was still looking for a consistent style, because some of these designs just look old and, compared to the later Rift set, rather ugly.
Minstrel set. Confusingly the new minnie set from BG is also called Armour of the Silver Voice.
Lore-master set. The robe design is really unique, but sadly it doesn't dye that well. Also, revenge of the Tea Cosy Hat!
Runekeeper set, which stands apart from the other armours since it was created over a year later than the first sets and doesn't actually look all that bad (the discontinued Ettenmoors version was especially cool-looking!).
