Loki was made to combine some stand-alone command line tools, like the bgp_cli, the ospf_cli or the ldp_cli and to give them a user friendly, graphical interface. It gave its modules the opportunity to base upon each other (like combining ARP-spoofing from the ARP module with some man-in-the-middle actions, rewriting MPLS-labels for example) and even inter operate with each other.
