About Javelins via the Anthem Wiki:
Javelins are powered exosuits worn and piloted by Freelancers when venturing into world beyond Fort Tarsis. They grant their wearers superhuman capabilities and are heavily modifiable, allowing for a number of unique individual models.
The general design of javelins is influenced significantly by Shaper technology, and the exosuits are among humanity's most cutting-edge technologies. Javelins are meticulously handcrafted by Arcanists rather than mass-produced, and are subjects of reverence due to their extraordinary nature.
