Curious of what a relay node is, I query back to the manual.
'A relay node is used to extend the connection to the core system. Relay node can be any auxiliary devices that can transmit a signal linked to the core system wirelessly or tethered to the core system or a intermediate-to-high level relay node.
A high level relay node is any heavily powered auxiliary device such as a server unit, or any high powered supercomputer.
High level node can transmit between multiverses and isn't interfered by any barrier.
Intermediate level node devices can be any commercial devices such as a PC or a workstation.
Like high level node, intermediate can do the same but at a slower rate and can take a long-time to transmit through interference barrier.
Low level devices is any low powered devices such as a smartphone, smart-wearable, tablet, or laptop.
Low level nodes can only be able to accessed other nodes and won't be able to directly access the core system. To access the core system, low level node must communicate with other intermediate-to-high level nodes to directly access the core system.
To create a node, user must create a linked key. Linked can be anything such as a usb-drive for intermediate-to-high level devices or a simple card for low level devices.
Linked can be created by inserting the device into the core system and authenticating it as a linked key.
User can immediately create 20 link keys at the initial start and additional link keys can only be create every 168 hours / 1 week (system time). Linked keys are transferable and can be transplant into new devices reverting previous devices to return to its original states.
Linked devices are unbreakable and has a higher connection ranges and increased battery life for low level devices. It's suggested that intermediate-to-high level devices has a stable power source.
