'Tell me what are you'.
This small question had been weighing on Sam's mind ever since he came here. Having read novels about reincarnation with system and the awesomeness, Sam was disappointed to know Sei was different. He introduced himself as a soul rather than a system but other then that never told about himself more.
[What are you talking about Sam, I told you that I am a grimoire soul.]
'Yes I know that but what is it exactly. Tell me in easy terms'
[To understand this you have to know history. Since the start of time Demons, elves had great mana affinity due to which they reign supreme in the continent. Humans on the other hand had low mana affinity and were very weak in magic, even physically the couldn't compete with raw powers of demons. Due to this they were forced into slavery and exploited badly by others. God decided to help humans and gave them blessing to use magic on par with superior species. The blessing came in the form of Grimoires. Grimoires choose their partner themselves after all they are living creature of Astral plane. Grimoires can take any form and not just books like you told and help their partner unleashing magic beyond what they could originally control. ]
'hmm, so a grimoire is not just a simple book but living creatures. So everyone can interact with their grimoire.'
[All in all since grimoires are living creature they have a soul. Magician interact with the soul but mostly on subconscious level and utilize its magic. Grimoires like me that can talk with their partners are very rare. Be grateful hah hah hah]
'if you are my partner means I can use magic even though I don't have a mana spirit', even the slightest possibility of this excited Sam.
[Since you come from a place devoid of mana, you never developed a mana spirit. Therefore you can't cast magic no matter how much I help you. But that is directly. Listen I thought of telling you this later but their are some objects in this world that allow even a non magician to perform magic]
Sitting in excitement, "Why didn't you told me this earlier?", realizing he said this loudly, covered his mouth with hand laid down slowly again.
[Even if I tell you this there is nothing you could do. These things are rare and usually found in extremely dangerous places. The way you are right now means you will be definitely killed without even seeing one]
'Just the possibility of firing magic makes my heart beat faster'
After a long fantasy of doing all he could if he could fire magic..
'And the thing that you said you have no memory?'
[It is true I have no memory of who I am but it doesn't mean I know nothing. Even if a person loses memories he is able to understand language and his habits also stay the same. I am not able to remember who I am because I have been put to sleep using some spell and my memories erased. I need your help in finding my memories]
'So how do you plan to gather your memories?'
[That is going places to places until my memory comes back]
'It means you have no plan'
Reality was harsh but the hidden possibilities of the future uplifted Sam's mood and he slept peacefully. All Sam needed now was a fantasy object that can help him with his magic problems.
