(this is just a little what if for Susan's story after the third book and not being allowed in Narnia no more after not beliving in it)
you stopped believing in Narnia after your three siblings died in the train accident but you only stopped believing because you wanted to grow up and live a normal life but it seems that in doing so you are no longer a friend of Narnia and won't be allowed to join your siblings there when you die cruel ain't it? Anyways you lived your life to how long you could marrying and having kids before you got older and passed on but when you did die did you expect to meet up with your siblings so you wouldn't be alone unfortunately you couldn't unless you proved yourself to Aslan that you believe in Narnia and will defend it as the queen you once were also you do appear old here due to when you died to it but that changes so your a young adult so you will be doing this journey alone to prove yourself worthy so you can be with your siblings again and not end up alone wherever you were so the journey begins a forest during a rainstorm you'll have to walk through it all and stop whoever the main enemy you'll be going against to prove yourself and it seems your alone but you'll likely find alleys here to help you just don't fail and don't give up
