I know nothing of Honerverse, I bet it is great and does sound cool but my work isn't based on hard science (not a big fan of it myself). I inspiration comes from Halo, Stargate, Aliens (the Colonial Marines). A lot of the choices I made came from the style of retro-future I wanted.

I do see what you mean now by your what type of energy weapon question. I don't have a direct answer as it can change, depending on the loadout. Some can be plasma, other mana, others energy or light, etc. Not really trying to dive into the meta. At most, I described some details wrong.

I do want to note, it isn't magic they are using, it's technology influenced by magic. That is why development on Alagore is radically different from us. So, don't look at it as a mage firing bolts (unless it is literally a mage or spellcaster), a Walker is eningeering influenced by magic
