What mouthpieces?
Thus Bind-Runes are Runes woven together to compound their meanings synergistically towards this "solar" purpose of developing and strengthening the Will. Thus creating bind-Runes out of two Runes with very different meanings and energies will often not produce an even mix or synergy, but radically lean the construct towards one or another. This is particularly evident in the "compact" overlapping-stave method advocated by Armanen, which results in a Bind-Rune using the fewest number of lines or strokes.
