A

This is the letter 'A'. Pronounced 'ah', as in 'Bach', 'although', and 'call'.

This letter is the most dominant and commanding of the vowels, and rightly so: it is the first letter of Ai, meaning 'light'. Light is an important idea to the native speakers of Sennin, as it is the only blessing that their fiery guardian goddess could bestow upon them.

It is almost sheild-like in it's shape, protecting and embracing, but also dangerous if caught at an acute angle. Its current form evolved from an ancient form resembling an open box lying face-down, or a doorway, but the topmost line was later dropped to form an upright chevron symbol.
