== '''Packet structure''' == When the client sends a packet to the server, the first byte encapsulates its opcode. This specific opcode is encrypted with a value generated by the ISAAC PRNG seeded with a dynamically server generated key during the login block. The server decrypts it and associates the opcode to the packet's respective predefined size. If the packet does not contain a fixed size, the opcode will be followed by either a byte or a word - varying per packet - for its proper size. This is then followed by the payload.
