A quick recap of my latest post (TLTR) In no particular order:
Top Pokemon Rangers Aiden Rivers and Lola Howell arive in Viore.
Brent and Lily are attacked by odd characters in Knight-Like Armor.
Brent and Lily rescue a Shaymin
Brent and Lily are saved from a sticky situation by a mysterious trainer and his Feraligatr
A strange symbol has appeared on Lily's hand...
This post has introduced a collection of characters. Two Top Rangers, dispatched to Viore by the Ranger Union to deal with Team Royal Skies, a mysterious Trainer who uses a Feraligatr (Should be a no duh to guess who), and two odd characters who are trying to capture a Shaymin, but end up losing said Shaymin to Lily and Brent.
This also brings up a part of the Plot, the Legendary Signs. If you are a Legendary Guardian, not long after coming into contact with your Legendary Partner, a strange symbol will appear on one of your hands (Most likely your primary). This will lead to many new powers in the future, so keep that in mind.
That said, the way you find your Legendary Partners if you are a guardian, these will be related to specific minor plot points along the way. So basically, they will be released as the story progresses. You can obviously work with me on how they will be found, so feel free to send any ideas my way.
