Build the Iconian Hub on your Station and you can travel through the gateway to Haven. Haven is the only known source of Resonance Charge. At its centre sits the Iconian Gateway, which makes Resonance Charge on its own with no mining or fighting. You can upgrade it to Level 10. Each level raises the Charge it makes and unlocks more structures in the Haven Store. Resonance Charge buys shards, the fragments that unlock a structure, and pays for structure upgrades, including the Gateway. Mute your device before the first visit. The intro video plays sound that ignores your in-game audio settings.
Part of Haven starts under toxic fog, and you cannot build on it. Every Haven starts with an Environmental Stabilizer that clears the fog. Upgrading it makes more Resonance Charge, clears fog better and opens more room to build. A second Stabilizer is coming later to clear further areas. Together with the Gateway, it is your priority upgrade.
The Haven Store sells structures in four rarities: Common, Uncommon, Rare and Epic. Common structures are decoration only. Uncommon, Rare and Epic ones give an account-wide buff, which applies to your whole account and not just Haven. The buff grows as you upgrade the structure from Level 1 to Level 10. Spend shards on the buff that matches what you are short of, such as research time, ship parts or repair cost. Only the highest-level copy of each structure type counts for its buff and prestige, and only while it is deployed on the map. Do not spend Charge upgrading a second copy.
The announcement lists 17 buff structures: 4 Uncommon, 4 Rare and 9 Epic. Station: Quark's Bar (Epic) lowers G7 station material cost and Geothermal Generator A (Epic) lowers G7 station resource cost, both up to 500% at max. Research: Xenobiology Lab (Uncommon, 800%) and Replimat (Uncommon, 400%) lower research cost, and Processing Plant A (Uncommon, 800%) raises research speed. Ship cost: Processing Plant B (Rare, 500%) and Training Complex (Rare, 700%). Ship parts: Federation Embassy for Explorers, Romulan Embassy for Battleships and Klingon Embassy for Interceptors, all Epic, 700% at max. Repair: Maintenance Yard (Uncommon) raises repair speed by up to 500% and Memory Core (Rare) lowers repair cost by up to 1,000%. Defence: Hospital (Rare) adds up to 7,000% shield health and Klingon Opera House (Epic) adds up to 10,000% hull health. Combat: Hydroponics Dome (Epic) adds Isolytic PvP damage and Zhal Makh Temple (Epic) adds PvE Isolytic damage, both up to 750%, and Captain's Lounge (Epic) adds PvP Critical damage, up to 750%. An early version of the announcement listed a Frontier Pavilion, but the structure that shipped is the Hydroponics Dome. Maximum values may be tuned later, so check the in-game structure screen.
Structures can be dragged to any tile that is clear of fog, and removed and redeployed, so a layout mistake costs nothing. Special road tiles are available if you want to dress the base. A structure's buff and its Frontier Prestige count only while it is deployed on the map, so one in storage does nothing. You may place several copies of the same type for looks, but only the highest-level copy contributes. Do not spend upgrade Charge on a second copy of something you already own at a higher level.
Frontier Prestige is the score that ranks Havens. Each server, and each server region, has a leaderboard sorted by total prestige, and you can visit any Haven on it. You can also share your own Haven in chat. Pressing Help on another Commander's Haven gives rewards to both of you, up to three times a day. You are not limited to your Alliance. Do your three helps when you log in.
Ops 61+ players also earn Resonance Charge from both the Free and the Elite Battle Pass tracks. The Haven Arc's Elite Battle Pass gives a full unlock of the Epic Klingon Opera House (the Update 95 announcement spells it Operahouse). To unlock it you need a Level 1 or higher Iconian Gateway and 100 Klingon Opera House shards. Its buff raises hull health by 1,500% at Level 1 and up to 10,000% at Level 10. Unlocking it adds 200,000 Frontier Prestige, which helps push the Gateway to higher levels. During the Haven Arc it was sold only through the Elite Battle Pass and was not in the Haven Store. Check the Store before assuming that is still true.
Update 95.1 made Haven easier to live with without changing its numbers. The fog looks better and runs more smoothly. The Dismantle page shows more clearly which resources you get back and whether the buff stays active. Structure names, levels and buffs are easier to read. A structure at its maximum level no longer shows a pointless upgrade button.
If you are below Ops 61, save your station resources for the Hub and read the Special station buildings guide to plan your space. You can look at other players' Havens but cannot build your own.
