Avalonian Runes

Here's a simple language to start off the site! I discovered this cryptogram by accident a few years ago upon the release of the Unforgiven Dead gauntlet. I noticed that many of the banners looked alike, but some had English and others had strange runes. I recognized some of the runes as Norse, but others were completely foreign to me. I already knew of a book in the Castle Avalon Library that had runes, but unfortunately they didn't match up:

However, I decided to take a closer look at the banners in the gauntlet to see if there were any cryptograms, and it turns out the same message is copied on all of the banners: Sluagh Slugfest. Yeah, I have no clue what that means either, but I was able to match up letters to the runes:

So, the Avalonian Runes from the Unforgiven Dead gauntlet are translatable, however I still have not deciphered the symbols found in the book. I personally think that they're two separate languages--if the book symbols can even be considered a language at all--but for now there are no other examples of each to find until another Avalon-themed update rolls around. 

After recently finding another set of these Avalonian Runes while playing the gauntlet, I realized that they were actually based in a real-life alphabet: Anglo-Saxon Futhark. While Futhark itself is Norse (see the Bear tab), Anglo-Saxon Futhark was adopted by the early folk of the British Isles, where Avalon, and subsequently the Unforgiven Dead Gauntlet, take place. Using the known runes of Anglo-Saxon Futhark, I was able to make a translation table below:
