Hi
I've as a feeling that you will not like at all, what is following
- the Templar slogan was;
"Non nobis Domine, non nobis, sed Nomini Tuo da gloriam"
Translation :
"Not to us, O Lord, not to us, but for the glory of your name"
nothing with T.unis   
 
- Louis / X, should be in fact Louis IX (9th), why him ?  
 
- Avalon, or Avallon ... heaven for Catholic ??? 
from where did you get this information  
are you not confusing with Arthurian legend ?? 
- the kufic writting on the blade, doesn't give a single word in Arabic 
- the sign "MLLCVV" in Roman date, is a non sense, means nothing coherent, 
here the equivalence "1000+50+50+100+5+5"  
if they want write 1255, should be MCCLV
Louis IX death was in Tunis in 1270
Louis X  (1289/1316) be King only 2 years 1314/1316, and did nothing of special
but it's his father "Philippe le Bel" (1268/1314), King from 1285 to 1314 who destroyed the Template Order
In conclusion, a fantastic rigmarole  
 
it seems a good tinkering to make sensational and lure the gullible 
 
sorry for you, if I'm correct, 
anyway not a single historical reference is matched   
all the best
