Tales of Symphonia a new comrad?

Our heroes from both worlds are coming close to visiting the temple of darkness where they will not only meet shadow but a new partner to join their ranks so. For starters the back-story of our new mysterious figure

His name is Matthew Apollyon and her is a half elf, he is a gifted mage as well as a sword fighter. He lived near heimndall the village of the elfs but, since he was a half breed he was constrained to the outskirts of town with his parents. When the pope decreed that a half elf was to be working for Science or killed, his mother went in willingly taking him with her as his dad ran like a coward to the village of the elfs .Since he was pureblooded and he asked if he could be the scholar of the elfs. After working for many years in the basement of sybak his mother fell ill and was offered the choice to be a subject for the cruxies crystal experiment or left to die in a cell by her self. Instead of going trough the pain of loneliness she asked her son who was 11 at the time to conduct the experiment on her, he followed knowing full well what would happen and kept the cruxies crystal she had made from herself and the dragon pendant she gave him with him always. Soon after something happened that he could not believe; he found a way to break out. He fled using any means of transportation he could find in search of a dwarf to make a binding spell so he could use the crystal. He had finally found one named Altessa with a strange girl named Tabitha, he explained his story to the dwarf and Altessa responded by saying:

Altessa: ill make the in-graving but where will you go after this?

Matthew: i don't really know a place that no one goes where its dark

Tabatha: may i suggest the temple of darkness their is a summon their that is dark and keeps it that way

Altessa: Tabatha sending this child to the temple is to extreme

Matthew : no i think i will go thank you miss,by any chace do you mind if i camp outside you re house?

Altessa : son you can sleep in hear i don't mind ,Tabatha make some food and get him a bed to sleep in

Tabatha : yes sir

Matthew : you don't mind tha half elf

Altessa : i m a dwarf i could care less what race you are

Matthew : thank you sir

2 days later the in-graving was done so i bid good bye to altessa and Tabatha and headed towards the temple of darkness near the capital of meltokio All i saw was pitch black darkness the only thing i could see was some glowing crystals laying around the floor in the two days with altessa he thought me how to make crystals into light sources like candles and such that would never run dry so i did exactly that created a candle but not a typical red candle but a blue one as i explored the inner regions of the temple of darkness i met with small blobs they keep following me so i searched for all of them as i went down trough the many corridors i found them the last one at the beginning of the alter of the summon but they made one giant blob that ended up turning into the summon itself and began to speak to me

You re a good child and by the way you carry you re self you look like you re also a good fighter as talking inside my head the only response that i could give him was that i know magic and swordplay but that is all i know of fighting he asked for my blade and so i gave that of which he asked he swallowed it (if just fusing it with his body counts) then told me that only those with the eyes pure and strong could find him and restore him would be receiving his trust so out of his body came two blades a short blade with a hollow point in the middle and a long katana with in graving on it dark and purple was its color and only thing i could say was thank you and asked if i could stay in his Company the only thing he said was that i was to get my own food he and that i had one other condition

Matthew : and this condition would what lord of shadows

Shadow : call me shadow , its to defeat the monster that is in the room behind my alter and that would be you re room if you defeat it it has link two the other floors as well

Matthew : as you wish my lord

As i went into the room their was a manticore which my first idea was that if it has a snake for a tail cut it off i used my own art called demon slash its like demon fang but in the air it cut off the tail and slowly i cut it bit by bit and won shadow was waiting for me and said

Shadow :you excel in combat you are welcome to my temple and i will teach you how to use dark magic for destroying that menace to my darkness

Matthew : that you shadow

As i lived in the temple a period of 20 years passed in which i never saw the light i am now 35 solemnly training and gaining experience from the monsters that lived in the temple i found books left behind researcher that keep me entertained as well intel one day that i was reading when i felt a different smell in the air when suddenly shadow apperd before me and said

Shadow : a summoner is cumming to make a pact i will do as i did with you very long ago protect my alter please when i arrive don't intervene

Matthew : as you wish my lord
